5167e5cd64 archive/zip: only consider UncompressedSize when checking dirs
CL 454475 switched from checking CompressedSize to UncompressedSize
when determining if we should consider an archive malformed because
it contains data and added a test for an example of this (a JAR). We
should also remove the hasDataDescriptor check, since that is basically
an alias for CompressedSize > 0. The test didn't catch this because we
didn't actually attempt to read from the returned reader.

185e1a7b27 runtime: prioritize VDSO and libcall unwinding in profiler
In the profiler, when unwinding the stack, we have special
handling for VDSO calls. Currently, the special handling is only
used when the normal unwinding fails. If the signal lands in the
function that makes the VDSO call (e.g. nanotime1) and after the
stack switch, the normal unwinding doesn't fail but gets a stack
trace with exactly one frame (the nanotime1 frame). The stack
trace stops because of the stack switch. This 1-frame stack trace
is not as helpful. Instead, if vdsoSP is set, we know we are in
VDSO call or right before or after it, so use vdsoPC and vdsoSP
for unwinding. Do the same for libcall.

Also remove _TraceTrap for VDSO unwinding, as vdsoPC and vdsoSP
correspond to a call, not an interrupted instruction.

Fixes #56574.

ad55b878e7 runtime/cgo: add .file directive to GNU assembly files
Without it, at least on ARM64 with older BFD linker, it will
include the file of the object file (which is of a temporary path)
as a debug symbol into the binary, causing the build to be
nondeterministic. Adding a .file directive makes it to create a
STT_FILE symbol with deterministic input, and prevent the linker
creating one using the temporary object file path.

45f5ef4ed7 cmd/go: remove TestScript/version_buildvcs_git_gpg
This was a regression test added for a 'git' command line
used for build stamping. Unfortunately, 'gpg' has proved to
be extremely fragile:

* In recent versions, it appears to always require 'gpg-agent' to be
  installed for anything involving secret keys, but for some reason is
  not normally marked as requiring gpg-agent in Debian's package
  manager.

* It tries to create a Unix domain socket in a subdirectory of $TMPDIR
  without checking the path length, which fails when $TMPDIR is too
  long to fit in the 'sun_path' field of a sockaddr_un struct (which
  typically tops out somewhere between 92 and 108 bytes).

We could theoretically address those by artificially reducing the
script's TMPDIR length and checking for gpg-agent in addition to gpg,
but arguably those should both be fixed upstream instead. On balance,
the incremental value that this test provides does not seem worth the
complexity of dealing with such a fragile third-party tool.

Updates #50675.
Updates #48802.
Fixes #57034.

5efa4dab91 cmd/go: skip TestScript/mod_replace_gopkgin
(Until it can be made hermetic.)

The gopkg.in service has had a lot of flakiness lately. Go users in
general are isolated from that flakiness by the Go module mirror
(proxy.golang.org), but this test intentionally bypasses the module
mirror because the mirror itself uses cmd/go to download the module.

In the long term, we can redirect the gopkg.in URL to the local
(in-process) vcweb server added for #27494.

In the meantime, let's skip the test to reduce the impact of upstream
outages.

For #54503.

1711f953e4 cmd/api: track deprecations
Deprecating an API creates notices that go out to potentially
millions of Go developers encouraging them to update their code.
The choice to deprecate an API is as important as the choice to
add a new API. We should track those and make them explicit.
This will also ensure that deprecations go through proposal review.

6a70292d1c go/internal/gcimporter: load cached export data for packages individually
Previously, we were using internal/goroot.PkgfileMap to locate
cached export data. However, PkgfileMap regenerates export data
for the entire standard library, whereas gcimporter may only need
a single package.

Under the new approach, we load the export data (still using
'go list -export') for each GOROOT package individually, avoiding work
to rebuild export data for packages that are not needed.
This is a tradeoff: if most packages in GOROOT are actually needed, we
end up making many more calls to 'go list', and may build packages
sequentially instead of in parallel (but with lower latency to start
using the export data from the earlier packages).

On my workstation, starting from a clean cache for each run,
this reduces the wall time of
'go test go/internal/gcimporter -run=TestImportedTypes'
from 22s real time (2m10s user time) to 6s real (27s user),
and only increases 'go test go/internal/gcimporter' from
28s real (2m16s user) to 30s real (2m19s user).

Updates #56967.
Updates #47257.

The test attempted to find all stdlib packages by scanning

Now that .a files are no longer being placed there, the test is a
noop. Fix this by using go list std (and filtering out testonly
packages) and trying to import all of those to recreate what the test
intended to do.

This also removes a dependency on the pkg/$GOOS_$GOARCH directory
which will stop being produced by dist in CL 453496.

8fd2875c3e go/types, types2: make the new comparable semantics the default
Ordinary interface types now satisfy comparable constraints. This
is a fully backward-compatible change: it simply permits additional
code to be valid that wasn't valid before.

This change makes the new comparable semantics the default behavior,
depending on the Go -lang version.

It also renames the flag types2.Config.AltComparableSemantics to
types2.Config.OldComparableSemantics and inverts its meaning
(or types.Config.oldComparableSemantics respectively).

Add new predicate Satisfies (matching the predicate Implements but
for constraint satisfaction), per the proposal description.

Adjust some existing tests by setting -oldComparableSemantics
and add some new tests that verify version-dependent behavior.

The compiler flag -oldcomparable may be used to temporarily
switch back to the Go 1.18/1.19 behavior should this change
cause problems, or to identify that a problem is unrelated
to this change. The flag will be removed for Go 1.21.

791f758075 archive/zip: tolerate compressed directories with zero uncompressed size
In CL 449955 we made reading of directories with associated file data
an error, since it is a "must not" in the zip specification. It turns
out that a number of implementations make the mistake of not setting
the correct compression method on directories (in particular the Java
jar tool does this when storing the META-INF directory). If the
compression method used is not 0 (stored) then the compressed size of
the directory can be > 0, despite the uncompressed size still being 0.

Since this mistake is not uncommon, we are forced to tolerate it. We
still fail if the recorded uncompressed size is > 0, which should be
a significantly harder mistake to make.

34ab0bcc5e crypto/ecdsa: verify validity of signature parameters in Verify
CL 353849 removed validation of signature parameters being passed to
Verify which led to two distinct problems. If passed a R or S == 0,
encodeSignature would panic since it expects them to be non-zero.
encodeSignature would also normalize (i.e. make non-negative) parameters
by zero padding them, which would result in a signature being passed to
VerifyASN1 which did not match the input signature, resulting in success
in cases where it should've failed. This change re-adds the verification
that 0 < r,s < N before calling ecnodeSignature.

This was caught because tink runs the wycheproof ECDSA vectors against
Verify, where we only run the vectors against VerifyASN1. We should be
doing both.
